Whine-aggregating service Yelp went public today, and is currently trading at $24.60 a share, which values the company at around $1.43 billion, according to Reuters. If this IPO were a Yelp listing, there would be a bunch of reviews like: "Not a bad IPO when you're drunk at night and nothing else is open, but WAY WAY WAY over-priced for what you get."
